    Cyclohexenone Construction by Intramolecular Alkylidene C−H Insertion:  Synthesis of (+)-Cassiol
    摘要:
    We report new procedures for stereoselective cyclopentene and cyclohexenone construction employing the alkylidene carbene C-H insertion reaction. Described are diastereoselective insertion into methylene and enantiospecific insertion into methine C-H bonds. The latter case leads directly to the enantioselective synthesis of (+)-cassiol (1).

  • A New Catalyst for a Pd Catalyzed Alder Ene Reaction. A Total Synthesis of (+)-Cassiol

    日期:1996.1.1
    conditions. Two variables proved key in the development of a new catalytic system that has proven to be effective, the absence of traditional ligands and the choice of acid. An effective synthesis of (+)-cassiol was accomplished in which this new reaction played a key. A lipase served to introduce the chirality, and a palladium(0) catalyzed reaction was important in elaborating a side chain. The final adjustment
    在抗溃疡剂 (+)-cassiol 的合成策略的背景下,探索了钯催化的烯炔环异构化的范围,从而产生了新的催化系统。在模型研究中,六元环形成的影响、系链中羰基的存在以及烯烃的空间位阻共同阻止了“标准”条件下的环异构化。两个变量被证明是开发一种已被证明有效的新催化系统的关键,即传统配体的缺乏和酸的选择。(+)-肉豆蔻醇的有效合成已经完成,其中这一新反应起到了关键作用。脂肪酶用于引入手性,钯 (0) 催化的反应在制作侧链时很重要。

    An enantioselective total synthesis of (+)-cassiol 1 possessing potent antiulcerogenic activity has been accomplished by using an efficient construction methodology of the asymmetric quaternary carbon center via a highly diastereoselective intramolecular [3+2] dipolar cycloaddition reaction of the nitrile oxide 10 as a key step.

  • Enantioselective Total Synthesis of (+)-Cassiol
    作者:Krastina V. Petrova、Justin T. Mohr、Brian M. Stoltz
    DOI:10.1021/ol802410t
    日期:2009.1.15
    An enantioselective total synthesis of (+)-cassiol is reported. The complex derived from Pd-2(pmdba)(3) and enantiopure t-BuPHOX ligand catalyzes enantioconvergent decarboxylative alkylation to generate the quaternary carbon stereocenter at an early stage. The overall synthetic strategy involves a convergent late-stage coupling of two fragments. The synthesis features a longest linear sequence of eight steps.

  • Detours en route to a total synthesis of (+)-cassiol
    作者:Marı́a I. Colombo、Juan Zinczuk、Marı́a L. Bohn、Edmundo A. Rúveda

    日期:2003.3
    A synthesis of the antiulcerogenic compound (+)-cassiol 1b has been achieved in 43% yield starting with lactol (S)-2 and sulfone 26. This short and efficient synthesis features the one-pot Julia olefination reaction of the sodium anion of (S)-2 with 26, through the key intermediate (-)-9. This synthesis has been developed as a result of exploratory experiments including different olefination reactions on 2. An attempt to synthesize the intermediate 9 by an intramolecular aldol condensation approach of the open chain precursor 4 is also described. (C) 2003 Elsevier Science Ltd. All rights reserved.
